Abstract
An exhaust gas housing for a gas turbine is provided and includes a support structure, which, arranged concentrically, includes an outer ring and an inner ring which are interconnected by radially arranged struts, and a flow liner, which is attached inside the support structure and, arranged concentrically, includes an outer liner and an inner liner which are interconnected by radially arranged liner ribs. The liner ribs each encompass the struts of the support structure, and the outer and inner liners inside the support structure form an annular passage for the turbine's hot exhaust gases. The liner ribs are welded together from front and rear parts in the flow direction, forming welded seams which extend axially in the outer liner and in the inner liner up to the liner edge. End rings, which cover the welded seams at the liner edge, are welded on the liner's rear edges for reinforcement.
